Starter Solenoid Test

1. Connect heavy jumper wire on starter relay between battery and solenoid terminals. If engine cranks, perform starter relay test.
2. If engine does not crank or solenoid chatters, check wiring and connectors from relay to starter for loose or corroded connections.
3. Repeat test and, if engine still does not crank properly, repair or replace starter as necessary.
